alt Hacker NewsOne thing I seem to struggle to understand is, a simple invite code system is showcased, but how does host Alice in one country know how to contact host Bob in another country with just the invite code? This seems to require a coordination server at least right, or does the invite embed some sort of information that'd allow Bob to directly reach Alice with just the invite code?

I think for this kind of system to work, there has to be SOME kind of public/shared server to do the coordination. If the inviting node is behind a firewall then no amount of information can enable a guest node to connect to it without a node reachable by both.
Iroh or n0 seems to solve that. It's they're underlying network protocol. When you're behind some cgnat, iroh falls back to public iroh relays hosted by n0: https://docs.iroh.computer/concepts/relays#public-relays
However you could self host one of these on a public server you own. Then you're independent.
